description
Layout of a 10 bit digital to analog convertor.
pre lab
For this pre lab I complited tutorial 1, and a cercuit is made with 10K ohm resistance.
This shows how to measure the length and wedth.
when extracted the resistance was 0.24K ohms off, 
Lab procedures:
Calculation
of the lenth and width of N well resistor is required in this lab.
R=p*(L/W) R is the total resistance, p is the sheet resistance, L is
the length, and w is the width. The width should at least be 12 lambda,
which is about 3.6um, and the total R is 10K ohms, and from the
formula we can find L = 45um. The 10kN well resistor that was created in pre lab is used here to create the layout of the DAC.
This is the 1 bit DAC which has 3 resistors, so we need 10 more like this.
this are the 10 bit, obtained by combining the 1 bit.
this is the DRC of the design
The file was extracted to make LVS.
The Lvs was done as seen below but it keeps giving me error.
